Objective To evaluate the effectiveness and safety of BiPAP non-invasive ventilation on COPD patients during acute exacerbation(AECOPD).Methods 20 COPD patients were ventilated using BiPAP non-inva- sive ventilation through a nose or mouth-nose mask.Their vital signs(RR,HR and BP)and arterial blood gases indi- cators(pH,PaCO_2,PaO_2 and SaO_2)before and after ventilation were monitored and the clinical effectiveness was ob- served.Results The vital signs and arterial blood gases indicators of 17 of the 20 AECOPD patients were improved. PaCO_2 was lowered,pH,PaO_2 and SaO_2 were elevated,and the difference before and after ventilation was statistically significant(P<0.05).Conclusion BiPAP non-invasive ventilation can improve the vital signs and physiological in- dicators of AECOPD patients,relieve their respiratory muscle fatigue and prevent them from exacerbation of respira- tory failure,thereby lower the need for endotracheal inrubation.

Objective To explore the efficacy and safety of modified vaginal paravaginal repair (VPVR) in treatment of symptomatic paravaginal defect cystocele(PDCC). Methods This study was an observational case series of 52 consecutive women in Beijing hospital from January 2007 to August 2009, with symptomatic paravaginal defect cystocele. Among them, 6 patients had anterior wall colporrhaphy. Preoperative and postoperative pelvic evaluations were performed with the POP-Q system. All the cases underwent vaginal approach to paravaginal repair, 49 cases underwent vaginal hysterectomy simultaneously. Patients were followed up for 1 to 24 months. Criteria for objective cure were defined as the anterior vaginal walls at grade 0 and firmly apposing to the lateral pelvic sidewalls.Results Of the 52 patients, 30 had grade Ⅱ , 17 had grade Ⅲ, and 5 had grade Ⅳ paravaginal defect cystocele. In all patients the VPVR was performed successfully. No complication happened during and after operation. The average operation time was (65 ±18) min (45-110 min) and estimated blood loss was (95 ± 27) ml (50-200 ml). Patients were followed up postoperatively for 3 to 24months, with a mean of (10. 1±3.1) months. The PDCC recurred in 6 cases, 5 patients had grade Ⅰcystocele and 1 had grade Ⅲ cystocele. Conclusions The vaginal approach to the correction of paravaginal defect cystocele is highly effective in our population.

Sperm ultrastructural abnormalities are often associated with sperm motility, the integrity of genetic material, and the fertilization potential. The investigation of sperm ultrastructural abnormalities is based on the evolution of microscopy techniques. In his paper, we review the improvement of the microscopy techniques and the ultrastructure of several specific morphological defects and he apoptotic spermatogenic cells in order to expound the significance of sperm ultrastructural observation in clinical practice. We deem it necessary to analyze the sperm ultrastructure before exploring the pathology and adopting assisted reproductive technology for some special patients with teratozoospermia.

Objective To document peritoneal tuberculosis mimicking ovarian malignancy in elderly post-menopausal women and to review pertinent literature.Methods The records of 3 women with peritoneal tuberculosis who were managed at Beijing Hospital from January 2003 to September 2009 were reviewed.Results Three patients with peritoneal tuberculosis mimicking ovarian malignancy all presented with the classical symptoms of advanced-stage ovarian carcinoma,including ascites,abdominopelvic masses,elevated serum CA125,bloating and progressive emaciation.Two patients received laparotomy revealing peritoneal tuberculosis but no malignancy.All the patients were treated with anti-tuberculosis chemotherapy.Conclusions Medical awareness of peritoneal tuberculosis is still lacking and many women with this disease are initially thought to have ovarian malignancy and undergo unnecessary extended surgery.Laparoscopy including biopsies seems to be a sufficient and safe method to provide diagnosis of peritoneal tuberculosis.If laparoscopy is not feasible,laparotomy should be performed.Ascites and high level of CA125 do not necessarily indicate that the clinical picture is malignant in post-menopausal women.

Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.

Purpose To prepare monoclonal antibody against hCG. Methods Balb/c mice were immunized with hCG, and spleen cells from the mice were fused with myeloma cells SP2/0 at ratio of 5:1. Positive clones were screened by indirect enzyme-linked-immunoadsorbent assay (ELISA) ,then the clones were subcloned by limiting dilution and amplified further. After intraperitoneal injection of hybridoma cells, mouse ascites antibody was prepared. Titres and specificity of the ascites antibody were identified and determined by indirect ELISA. The ascites were purified by protein A affinity chromatography. Results Two strains of hybridoma cell lines obtained could secrete MAb stably. The titre of MAb of cell culture supernate is more than 10~(-3), and the titre of prepared ascites MAb is more than 10~(-7).The purity of the obtained monoclonal antibody was more than 98% and recovery reached 75 % after purification. Conclusion The obtained two strains of hybridoma cell lines can secrete MAb stably. The monoclonal antibodies can be used in the research of early pregnancy and tumor diagnosis .

OBJECTIVETo compare therapeutic effects between arthroscopic medial retinaculum plication and plaster external fixation for the treatment of acute patellar dislocation.
METHODSFrom February 2006 to October 2012,29 patients with acute patellar dislocation were divided into two groups: operation group and non-operation group. The patellar dislocation duration was 2 weeks. In operation group, there were 7 males and 10 females, with an average age of (16.2 ± 6.2) years old, and the patients were treated with arthroscopic medial retinaculum plication. In non-operation group, there were 5 males and 7 females,with an average age of (16.3 ± 5.0) years old,and the patients were treated with plaster external fixation. The Kujala scores, patellar tilt angle measured on CT film, apprehension test and recurrence rate of patellar instability were observed before and 1 year after treatment.
RESULTSIn operation group, the pre-treatment and post-treatment patellar tilt angles had no statistical difference, but the post-treatment Kujala score was lower than that of pre-treatment; while in non-operation group, the post-treatment patellar tilt angle was larger than that of pre-treatment, and the post-treatment Kujala score was lower than that of pre-treatment. At 1 year after treatment, the patellar tilt angle (21.2 ± 5.3) of patients in non-operation group was larger than (13.5 ± 3.5) of operation group, and the Kujala score 73.3 ± 10.5 of patient in non-operation group was lower than 84.1 ± 5.6 of operation group.
CONCLUSIONDuring 1 year after operation, arthroscopic medical retinaculum plication is a more effective treatment for acute patellar dislocation compared with plaster external fixation.
